Since I only know a little bit about Linux, I have included only the proofs which are publicly available on the Internet.I would be happy if the Windows and Mac OS X users correct these operating systems and the documents which are publicly available on the Internet can be added/supplemented. I'm also not sure if I've thought of everything, so I'll add point 9. If an item is irrelevant, please also correct this with reasons.

GENERAL:PLEASE IMMEDIATELY FOR AN OBJECTION/... ADD THE CORRESPONDING LINK(S) AS EVIDENCE.ME AND YOU DON'T WANT TO EXPLORE THE OTHER SIDE WITH A SEARCH ENGINE REQUEST.

1.) Can be co-designed/programmed by the operating system user, direct communication/participation.:

Lin - [~X] [subjective]<== My personal opinion: Depends partly on the special audio/graphic/... manufacturers if they support the OS. In general, driver support and support for system/hardware/software is (very) good.[/subjective]

9.) The user SW is innovative:

macOS - [X]

Win - [X]

Lin - [~X] [subjective]<== My personal opinion: Depending on the liveliness of the Software - GNU-Projekt or the provision of the special audio/graphic/... software manufacturers.[/subjective]

If you buy a soundcard that isn't supported by the kernel, or you are unable to install the necessary kernel easily, then it won't work in Linux. In Windows and osx it will.

This is why I ALWAYS choose an audio interface that works in Linux. Duh.

Well you needing knowledge of something isn't an advantage of the operating system and is quite opposite of the purpose of computers in general. It's a huge flaw if the OS is not compatible with the latest products and/or technology when another does. If other operating systems support it then there no contest, and this isn't an uncommon scenario. Linux fails in this area in comparison because of the very nature of it. That's not to say it fails altogether though, only as a comparison.

I do not use "other" plugins. What plugin formats are important?Which plugin formats run on which operating system(s)?</EDIT>

@DriverIt's not just the audio drivers. And also some audio drivers may have limitations under GNU/Linux that you don't have with Win/OSX - so under those operating systems you have all functions. Example: hdspmixer has no MIDI support under Linux.But also other drivers, also operating system relevant drivers, could behave differently under GNU/Linux or not at all.For example, if a graphics card doesn't work properly - your system becomes unstable and not all functions run/are fully supported - it can be annoying.The GNU drivers and kernel developers are doing their best. But with little will of the manufacturers to run the hardware under a certain operating system - among other things passing on the documentation - it is damn difficult. There are only a few GNU drivers and kernel developers. Some people do that on the side. A friend of mine and I had contacted a nice RME ALSA driver developer. We tried to make the AIO work under GNU/Linux. Successful. THX \o/ The ALSA driver developer was a student (according to e-mail).

With your help your desired hardware can work under GNU/Linux. Contact the appropriate driver developer. Works with the developers.Start developing.
